I've been researching what filters I should use when photographing in B&W and haven't found much info on it... First, know that I will be using film and do not want to/can not use photoshop in any way. I would like to know what filter to use to turn up the contrast and keep everything in the photo interesting. I need to know what brand of filter is a quality brand, and what kind of filter/s I need... I looked around Adorama and there are more filters/kinds of filters there than I could ever look through in a life time... so I need to know what's good and what's bad. Also, is there any price range that I should be looking at? Like... $10-$30 is crap... $35-$65 is pretty good... etc.... Is it that way for Filters? There are a lot of questions I have.... so I'll just stop now and get some of these answered. Thanks!
